As a result, a null value in the JSON would cause us to throw and block pipelines from running. This PR fixes a number of issues: * Properly handle null JSON values in `ProxyInvocatinHandler.Serializer` * Establish a common pattern for handling errors during display data collection, via `DisplayData.from(Throwable)` * Implement resiliency pattern in `ProxyInvocationHandler.Serializer` so bugs in `PipelineOptions` serialization do not prevent running pipelines.
